### Roborock Saros 10

### Roborock Saros 20 Flow

- House Digest (9/10): Floors came out about 90% clean with some crumbs left in corners. Mopping fully removed ketchup and barbecue sauce and left wood almost dry. It cleared a baby gate but got lost once and had underwhelming edge cleaning. [Source](https://www.housedigest.com/2284562/roborock-saros-20-flow-review/)
- EFTM (92%): Australian review gave vacuuming 93%, mopping 93%, app 92% and features 93%. It cleaned dried jam and tomato sauce, needed two passes for Vegemite and struggled with crumbs near cabinets. Charging was slow.
